To all whom it may concern:

p 'Be it known that'I, WrLLIAM L. WAfrERs, citizen of the United States,residin at Milwaukee, in the county of Milwau ee and State of Wisconsin,have invented a certain new and useful Improvement in Dynamo- ElectricMachines, 0 which the following is a full, clear, concise and exactdescription, reference being had to the accompanying drawin ,forming apart of this specification.

invention relates to dynamo electric macliines, having for its objectimproved features of construction and arrangement,

particularly of the field magnet and inclosing I, therefore, have theline of separation between the upper and lower halves of the casting insuch position that the poles and bearings will be cleared and straightuninterrupted paths offered for the finishing tools, and the arrangementof my invention will be best understood by reference to the accompanyingdrawings inwhich Figure 1 is a side view of a dynamoelectric motor, andFi 2 is an end view, showing the upper and ower halves of the casingseparate In this machine there are four oles, two vertical poles 1 and 2and two orizontal poles 3 and 4. If the upper and lower halves 5 and 6of the inclosing casing were divided on a horizontal plane passingthrough the axis of the armature shaft 7, the horizontal poles would bein the path of the laning or milling tools which would be used to planethe on aging edges, and a great deal of time would be consumed infinishing all the surfaces. I, therefore, have the line of divisionbetween thetwo halves along several planes.

'The line of separation runs first in horlzontal plane 8 which is abovethe horizontal pole 3 then in verticalplane 9 which is between the ole3' and bearmg'parts 10, then along the .fiorizontal plane 11, passingthrough the axis, then along vertical' plane 11'. between thehorizontal' pole 4 and bearing parts 10, then horizontallane 12 which isbelow the pole 4. With the construction there is noth-' mg in the pathbetween the oppositeedges in thevarious planes, and eachpath of thecasing can be laid on a machine bed and or planing tools can be carriedstrai ht across to practically cut and finish the e es in one o eration,and the finishing of t e edges, t erefore, becomes a-ver simple matter,the edges being also true, t us insuring a tight an erfect fit when thehalves are brought toget er. It will be noticed that the halves of thebearings are also finished during the same operation. With this soaration of the parts, the u per vertical an right horizontal pole an theupper bearing halves ma be cast integral wit an thelower vertical and let horizontal poles and the lower bearing section may be cast integralwith the lower or base section. This arran ement is very useful in thatwhen the top half is removed, as shown in Fig. 2, the armature shaftwith the armature can the upper section,

very readily be inspected or lifted from the along two vertical andthree horizontal planes. a

2. In a dynamo electric machine, the combination of an inclosing fieldframe comprising an upperand lower section opposite horizontal oles forthe field-frame, earings'disposed between the poles for supporting anarmature shaft, the line of separation lying in three horizontal planesdisposed respectively above the left pole, through the axis of thebearings, and below the right pole, and in two vertical lanes disposedrespectively between the lefif pole and the bearing, and between theright pole and the bearin 3. In a dynamo electric machine, t ecombination of an inclosing field frame. comprisin an upper and a lowersection,'horizontal fie d poles for the frame, bearings for the armatureshaft between the poles, the line of separation between the framesections assing along a horizontal plane disposed a ove the left, poleand along a vertical plane between the left pole and the bearings, thenalong a horizontal plane passing through the axis of the shaft, then ina vertical. plane between the bearings and the right pole, then in ahorizontal plane disposed below the right pole, the right pole and upperbearing sections being cast integral with the upper frame section andthe left pole and lower bearin sections being cast integral with thelower rame section.

In witness whereof, I hereunto subscribe 15 my name this 7th day 0fDeeember A. D., 1906.
